A mechanical blockage that prevents motor movement can also be the culprit. If the motor is mechanically stalled (e.g., a seized bearing, a jammed mechanical component), the drive will try to deliver ever-increasing current to overcome it, eventually hitting its limit and throwing the error. It is also worth checking for proper grounding: a missing PE connection to the motor can create erratic conditions that trigger the fault.
To conclusively determine whether the fault lies within the motor or the internal electronics of the power section, perform a module swap: simodrive 611 error 607
: If the 607 error moves to the new axis , the issue is located within the external cable, connector plugs, or the motor itself. A mechanical blockage that prevents motor movement can
Attempt to turn the motor shaft or ballscrew manually. If the axis is locked or highly resistant, decouple the motor from the gearbox or ballscrew. To conclusively determine whether the fault lies within
